Denver Short Term Ryegrass
Lolium multiflorum - SKU:
A long-season, tetraploid Italian ryegrass selected for seedling vigour and substantial winter growth.
Dynamic recovery from grazing and cutting
Extremely disease resistant
- Tetraploid Italian-type plant
- Designed to persist for 2-3 years under suitable conditions
MaturityA very late flowering plant designed to produce good quality feed late into the spring.
Days to flowering relative to Nui (0) = +16
Area of Adaption
- High rainfall and irrigation
- A reliable spring is essential to maximise production potential, due to Denver’s late flowering habit
Soil TypeDenver is best suited to well-drained loam soil types but adapts to a wide range of fertility levels and soil profiles. Tetraploids will cope with some water-logging for short periods of time provided the growing tip is above water. To maximise stand productivity, soil testing is advisable. Analyse soil and neutralise deficiencies with fertiliser and/or lime.
FertilityGood base rates of phosphorus are necessary for maximum DM production especially during establishment phase. DM production is directly related to nitrogen availability. Consult your Upper Murray Seeds agronomist or fertiliser advisor for nitrogen application rates.
Sowing GuidelinesSow at 25-30kg/ha alone or 5-15kg/ha when a component of a pasture blend. Sow seed no deeper than 1cm in a fine but firm seed bed. Sow into bared ground if direct drilling. Lightly harrowand roll to improve germination. Suitable for oversowing into an established stand. Pasture productivity is directly related to successful plant establishment.
Disease and Pest ManagementDuring emergence it is essential to monitor regularly for damage from insects such as RLEM and lucerne flea, and spray as required. Inspect during early stand life for populations of black-headed cockchafer and slugs. Contact your Upper Murray Seeds agronomist for spray application rates.

Weed ControlDenver is very competitive as both a seedling and established plant. Always use a knockdown herbicide to ensure you are sowing into a clean seedbed. Monitor for post-emergent weeds and spray as required. Use options such as spray-grazing for broadleaf weeds.
GrazingDo not graze Denver until the plant is well anchored and root depth is established. Carry out a quick in-paddock ‘grab test’ by hand to ensure stock cannot pull plants out of the ground. Denver should be rotationally grazed to maintain 2-3 leaves per tiller. If the stand is allowed to grow beyond the three-leaf stage, it may run to head earlier and there will be a proportional reduction in quality and productivity.
Feed QualityShort-term tetraploids such as Denver have 4 sets of chromosomes per cell resulting in bigger, darker leaves. This increased cell size has higher sugar and moisture content which is more palatable and digestible than diploid varieties.
